I agree. You guys are scaring the hoes.
I think the best way to convince her to do more lewd, suggestive things is to (unfortunately, as much as we simps hate to see it) get his fiance more involved. That may be the only way. If you can encourage her man to show up on screen and share together some more personal, intimate situations (could be innocent at first), then there's a higher possibility that she would not only address them, but act on them as well. Remember those gropey, laying-down, my boyfriend does ASMR on me, showing shoulders and such? We might be closer than we think. We just have to swallow the fact that his fiance will be involved, at least at the beginning.
She's not going to do XXX things on her own. Bring her boyfriend along, and connect her with more lewd ASMR folks like Simone ASMR, and such. That's the only way we can do it, I think.
